Dataseries-BarsInProgress-Volumetric

[tonynt]

Hello,

I use more than one dataseries in my script.

When I have in OnBarUpdate "if(State==State.Historical) return;" it works OK.
But when I add 2 x volumetric with eg
in configure AddVolumetric("MNQ 06-20", BarsPeriodType.Range, 3, VolumetricDeltaType.BidAsk, 1);
and in onbarupdate
NinjaTrader.NinjaScript.BarsTypes.VolumetricBarsTy pe barsType = BarsArray[2].BarsType as NinjaTrader.NinjaScript.BarsTypes.VolumetricBarsTy pe;
if (barsType == null) return;
NinjaTrader.NinjaScript.BarsTypes.VolumetricBarsTy pe barsType2 = BarsArray[4].BarsType as NinjaTrader.NinjaScript.BarsTypes.VolumetricBarsTy pe;
if (barsType2 == null) return;

and use it in the code eg like
"&&(barsType.Volumes[CurrentBar].GetAskVolumeForPrice(Highs[2][1])+barsType.Volumes[CurrentBar].GetAskVolumeForPrice(Highs[2][1]-1*TickSize)"

I get in the log tab the error message:
"Time Category Message
08.05.2020 10:28:00 Default Strategy 'Tx17xNQv1xAvolx1x2r': Error on calling 'OnBarUpdate' method on bar 1223456: Index was outside the bounds of the array."

What might be the reason for this log-message please?

Thank you!
Tony

Hello tonynt,

One problem in what you provided is that you are using "CurrentBar". That will be the current bar for the series which called OnBarUpdate not necessarily the volumetric series. You could try using CurrentBars[2] instead to see if that is the reason for the error.

You are also using other indexes in this syntax so at this point it would be best to reduce what you have and find what specifically is throwing the error.

Please let me know if I may be of further assistance.
